AI Technical Summary

Technical Problem

The existing Braille education system faces challenges such as low tactile sensitivity in people with acquired visual impairments, difficulty in learning Braille due to different writing and reading directions, and a lack of diverse and effective teaching aids, resulting in low proficiency rates among the visually impaired population.

Method used

A variable Braille output device and smart block system that includes a Braille code output module and a Braille output module with a dynamic output mechanism, allowing for the conversion of various input information types (images, videos, characters, voice, motion) into Braille and outputting it dynamically using a Braille output plate and actuator unit.

Benefits of technology

The system enables effective and efficient learning of Braille by allowing dynamic output of Braille characters, improving learning efficiency and accessibility, especially for those with low tactile sensitivity, and providing a versatile teaching aid that can be integrated with smart boards and applications.

Abstract

This variable braille output device comprises: a braille code output module for outputting a braille code on the basis of input information; and a braille output module configured to dynamically and variably output braille on the basis of the braille code that has been output by the braille code output module. The braille code output module comprises: an input unit for receiving, from the outside, information including at least one among an image, a video, a character, a voice, and motion; a character extraction unit for extracting a corresponding character from the information received by the input unit; and a braille code output unit for outputting the character extracted by the character extraction unit as a braille code. The braille output module comprises: a braille output plate having through-holes arranged in a predetermined dot matrix pattern; dot rods disposed to pass through the through-holes along the central axes of the through-holes with respect to each dot matrix; and an actuator unit configured to independently move the dot rods along the central axis of the through-holes on the basis of the braille code that has been output by the braille code output unit. Therefore, the braille output module can dynamically convert a character, indicated by the information received by the input unit, into braille and output the braille.
